To aZZw/zo'm it may concern; y

Be it known that I, JAams Bama, Ia citizen of4 the .United States,residing 1at Canton, in the c'ouiityoflStahrk and State of Ohio, haveinvented anewV and useful Cooling-Floor Tile, of which the following isa specification.` v i The object of'r'ny invention' is to produce aiioorvtiling of4 such construction .,tliat,

when a pluralit are* associatedftogether,,a

floor ofdesire dimensions may be4 produced, within which may becirculated a cooling iuid,such as,l cool water. The floor 1s of suchcharacter as to'beuseful in .rolling mills, glass houses. and otherbuildings where the operations areproductive ot oxcessive temperatures,the .invention being useful in rolling mills where the ,hot iron isdriven over the saine iio'orv'upon which the operatives are required top ass. y,

The accompanying drawings illustrate my invention. i t Figure 1 is anelevation of a rolling mill flankedI by my improved iioors.. Fig. 2 is apla'ni'n partial horizontal section; andliig. 3 a section on line 3-3 ofl1`ig.4.2. v ,l i'

The fundamental-.element of. my improved floor is a unit ti1eor block'l0 comprising top and bottom plates and side walls which thus yformahollow blockoflv suitable the water circulation dimensions havinesirable that the units 10 chamber 11. 1t is l be of considerable sizeyet the walls and top and bottom plates should not be too thick, ,y su

and for that lreason I arran e within the chamber 11 a series of verticapartitions 12 extending between the bottom and top lates and serving tothoroughlybrace an support said plates. The partitions 12 areinterrupted at suitable points 13 so as to defleet the water currents,and* opposite ond walls are provided with openings 14 which registerwith similar openings in adjacent lblocks so that the blocks may bearranged inv connected seriesby means of tapered bushings 15 ittin'openings 14 ressed fit. Il`he initial wa of the first lock of eachseries is provided with a tapped o ening' 16 to receive a supply pipe 16and tiis pipe is connected =by.a suitable union 17 with' amain;line;f.18. 'iThe'final block' 10 of each series vin""its''farthest'wall lisprovided with a tapped fopenin'g 19 for angegress -pipef' 20 wiicli is v4considerably smaller tlianthe supplyv pipe ljlsothat thereferably byv ii `nance ofthe cooling iiuid under circulation of Iwaterthrough the blocks will be undermaterialpressure. Any'desir'edynu'mberof series of blocks may be'. arranged, in parallel series and clampedtogether by bo ts 21 lying between adjacent series;- rectan ular`washers 22 being placed beneath eac clamping nut 23 so as to cover thegap between adjacent blocks andalsoso as to distribute the clampingpressure. Ind it desirable i'n the roduca tionofthes,e blocks toundercut .t iein at their lower longitudinal corners, as indi-4 cated at24,so as to form a; ocket for the rod21',,thu`s `making it possib e tobring the uppeiylongitudinal corners together witha reasonablej degreeof nearness as indicated a'tf25.v g Y In Autilizing this floor-tile Ifindl it desirableto provide a supporting.` floor 30,l conveniently ofjconcrete, and this floor is provided lwithvdra'inagechannels 3l lto take1care ofany,possible-leakages from the coolcooling rnediumfthedischarged. water may c be'carried to the various water boshes used`ready removal ofthe cores and the proper clearing of the interior.These openings are plu ge by plugs 36 which may convenienty be `of theordinary tapered screwthreadedxtype.

The provision of the small outlet pipes 20, and the consequentpossibility of mainteressiire, enables me to insure the most eliicientcontact between .the cooling fiuid and the walls ofthe block, therebyobtaining the greatest heat absorbing efi'ect.

By the use of these cooling floors it is-not only possible to protectthe feet of the person, but they also assist inthe cooling et theentire-atmosphere of the building in which they are placed.

The blocks may be produced from any suitable or desirable material,metal plate, terra cotta, cast iron, etc.

I `claim as my invention:

1. A cooling floor comprising a plurality of hollow Hoor-blocks arrangedin a series having internal connections connecting ad- ]acent blocks, asupply pipe and a disc arge pipe, said discharge pipe giving aneffective outlet smaller than' t e supply pipe.

2. A cooling floor comprising 'a plurality of hollow iioor-lilocksarranged y in a series having internal connections connecting adjacentblocks, a supply pipe, and a discharge pipe.

8. A cooling noor comprising a foundation flanked by a channel, a supplypipe laid in said channel, a lurality of hollow 'floorblocks laid end toend on 'the foundation and internally connected in series, connectionsbetween the interiors of one of said blocks and the supply pipe, and adischarge pipe leading from the series, said discharge pipe giving aneffective outlet smaller than the supplrpipe 4. cooling floor comprisinga `foundation flanked by a channel, a sutpp'ly pipe laid in saidchannel, a plurality o ollow floorblocks laid end to end on the`foundation and internally connected in series, connections between theinteriors of oneof said blocks andthe supply pipe, and a-discharge pipeleading `from the series.

5. A coolin floor comprising a lurality of sets of hoi ow floor-blocks,the locks of several sets -in parallel and discharges for seid este thead'acent under corners of the blocks being un ercut to form clamping-barchannels, l,and clamping bars extending through said channels parallelwith the nipple axes.

6. A cooling floor comprising a plurality of sets of hollow floorblocks, the blocks of each set connected in series, a supply pipeconnecting the 'interiors of the several sets in parallel and dischargesfor said sets the adjacent lundercorners of the blocks being undercutto' form clamping-bar channels and clamping bars extending through saidchannels.4

7. A coolingfloor com rising a plurality of sets of hollow floor-'blocrs, the blocks of each set connected in series by pressed-tit nipplesextending through adjacent walls, a supply pipe connecting vtheinteriors of the several sets in parallel and discharges for said sets.

'-8. A cooling floor comprising a plurality of sets of hollowfioor-'blocks, the blocks of each set connected 'in series, and a supplypi e connecting 'the interiors of the several s s in parallel anddischarges for said sets.

In witness whereof, I have hereunto set hand at Avonmore, Pennsylvania,this thirtieth day of July, A. D. one thousand nine hundred andthirteen.
